signed-as .to prevent the turning over of the engine, thereby avoiding any possibleinjury- 7 Be it known that I,'FRA K WCQLLARD, a

citizen of the United States, and resident of VBillericafcounty' of Middlesex, State of Massachusetts, have invented an Improvementin Pedal Locks for 'Automobiles, of

which the following description, in connection with the accompanying drawing, is a specification, like characters on the drawing representing like parts.

This invention relatesto improvements in pedal locking mechanisms for automobiles and the objectthereof is to provide a lock which can be quickly applied to the pedals of an automobile 'and which when applied will lock themechanisms for operating the machine in such positions as to' preventthe automobile from bing propelled in either direction' by its ngine or from being pushed or towed forwardly. In fact thelock issoideto thedriving mechanism from. the power which. might otherwise be obtained from thej engine;

The invention herein disclosed is illus-' trated as applied to the pedalmechanism' of an automobile of the well known Ford type and comprises locking means adapted to secure the high gear in mesh with the driving gear, the reverse gear in mesh with the driving gear and the brake pedal on, thatjis, in braking position or with theservice brake partially applied.

' A further object ofthe-invention is to in the manner aforesaid'but will also lock theffoot board against removal thereby pre-' transmitting mechanism; Y

A further object of the invention'is-to pro v vide a pedal lock of the character specified which cannot be removed by filing or sawing. Other objects and features of the invention 'will more fully appear from the following description-and accompanying drawings and will be pointed out in the annexed claim; :In the drawings, a r f g 5 Fig. 1 illustrates diagrammatically the position of the floor board of-aFord automo:

, bile with'the clutch, reverse and brakelevers lockedin such a manner as toprevent the i starting up of the automobile or its removal by pushing or towing,

These-levers extend upwardly through rthe floor board at different angles tothe plane of the same; I

The levers *1 and 3 incline forwardly, that is, toward the right,while the. reverse1ever'2 the machine in the customary manner.

inclines backwardly, that m the 1 a. The 7 floor board t 'of the automobile is inclined forwardly from the plane of the floorbof Th 'p'edal locking means comprises'a twopart plate consistingoffflat sections 6 and 1 having overlapping circularportions 8 which are securedtogether by a rivet 9 in a man- Y a walls 12, 13 which embrace tightly the edges ner similar to that in which portions of a folding rule are secured together. The sections 6 and 7 of the plate are provided With recesses of such a character that when the I edges of said sections are secured together the apertures will be in substantially the alinement illustrated in Fig. 2 of the drawofthe clutch and gear shaft lever 1} he section 6 is also provided with a recess 1st to receive and fit the reverse lever and lock the same aga nstthe inner edge of the plate 7;

.T he sections 6 and 7' are also provided with complementary recesses 15, 16 lliLVlIlg in clined walls 17 and 18 respectively to fitflthe edges or the brake lever 3 and to hold the same, when the edges of the sections are'togather, in braking position'. The outer or free ends o't th'e sections 6 and 7 of thelocking de-. vice are provided with upwardly extending integral lugs or flanges 1Q, 20, thefflange 19 extending, everthe edge thereof a considers ab efdistai c d sfi it dbf bi u ated I to present paralle eil c'tamo'rtise'to.

Furthermore, "the interlock; ingportions of the upstanding flanges upon thefree ends of the sections 5 and Get the, locking plate may be made integral with the plate and so constructed as; to render it quite difficult to saw through the mortise joint, particularly when the hasp of the 1001; h
